8.4 Selecting the valve types
When setting a valve, the operator generally must ensure that no command value and
no enable is applied to the VT-MSPAx-2X!
The desired valve type has to be selected by means of the two rotary switches, see
Fig. 4 item 4. The left-hand rotary switch sets the tens place, the right-hand rotary
switch the units place of the item. While you make the settings, test jack “v“ outputs
the selected rotary switch position as a voltage value in 100-mV increments.
The following valve types are available.
